Super secret. How to decode Base64 Basic Authentication!

When the server returns 401 and the header: WWW-Authenticate: Basic. The server wants you to send the username and password in this format: jeff:mypassword and then encode this as a Base64String. You can encode this with this code: string secret = Convert.ToBase64String(System.Text.Encoding.UTF8.GetBytes("jeff:mypassword"));. To decode a username and password from a header that you send (found in the Authorization: Basic" header) pass that string to this: string decodedSecret = System.Text.Encoding.UTF8.GetString(Convert.FromBase64String(secret));
